OS X El Capitan LogoApple today released a new version of OS X El Capitan Security Update 2016-003, fixing an additional kernel issue that could cause Macs running the operating system to freeze up and become unresponsive.

The 2016-003 Security Update for OS X El Capitan was originally released on December 13 alongside macOS Sierra 10.12.2, but was today reissued with the fix.

Customers who have not downloaded the security update at all will get the new version when updating their machines, while customers who previously installed the security fix will receive a supplemental update to address the freezing problem.

The OS X El Capitan Security Update 2016-003 Supplemental Update fixes a kernel issue that may cause your Mac to occasionally become unresponsive.

Mac users who are still running OS X El Capitan can download the update through the Software Update mechanism in the Mac App Store, and direct download links are also available (Standard Update/Supplemental Update).

The original 2016-003 update fixed a number of security vulnerabilities in the OS X El Capitan operating system.

Aren't there any reasonable apple users that don't moan and groan the same anti apple stuff every time the slightest little thing happens? And why don't you move to Windows and receive those very other day updates? That will give you lots to complain about.

I understand how complex computers have become and how hard it can be to prevent issues. I applaud Apple for what they do. I deplore users who love to complain for the sake of complaining. They should be banned from using Apple products, which frankly, are too good for them.
Smilies were invented to add some subtlety to online written communications. In this case, they communicate sarcasm and the emojis used were correctly employed.

Next time, when a contributor includes emojis, think about what made them consciously decide to include those in the post.

As a matter of fact, MORE people here should use emojis since there are a large number of readers for whom English is not their first language.

Thank you for reading. :D

Man 10.11.6 is running fine on my 12" rMB do I want to rattle the bee's nest ?
No. Wait until you crash, lose your data, scream so loud you have a stroke, and then update.

Ugh, ANOTHER security update? Can't apple EVER get ANYTHING right?

Is Apple still supporting Mavericks with any security updates if needed?
Not anymore. The oldest one still supported as such is yosemite, which will probably cease when macOS 10.13 is released.

But this El Capitan one updates the build number from 15G1212 to 15G1217.
